Abstract

For the first time, the time dependence of [H~2~O~2~] and [Fe^2+^] was followed during the aerobic oxidation of ethanol by Fenton's reagent. It was found that part of the ethanol was oxidized by dissolved O~2~ via the transient formation of H~2~O~2~. A model was set up based on FeO^2+^ as the key intermediate. Both one‐ and two‐equivalent oxidations of ethanol occur, the former producing radical species derived from ethanol. No free radicals derived from H~2~O~2~ play part in the system. The relevant rate constants or their ratios were determined. The mechanism accounted successfully also for the anaerobic oxidation of ethanol. © 2008 Wiley Periodicals, Inc.
